Share code between expo and deno

[chmac]

We have some code in nr-common and I think we can import it from nr-server but I can't import it from nr-app. There are all kinds of errors, some of which I thought I'd fixed in 99fd596 but it turns out, I haven't.

Goals:

• Typescript code in nr-common
• We should be able to use packages in nr-common (eg zod)
• Code should be usable from the expo app (nr-app)
• Code should be usable for deno (and probably from node)

Nice to have:

• Code should be imported without a build step
  • Using workspaces, you typically need to run pnpm i or similar after every change in nr-common which creates unexpected weirdness because changes don't immediately propagate
• TypeScript should be imported rather than *.js and *.d.ts

This has turned to be wildly difficult. I ended up copying nr-common into nr-server and even then there were still problems. Some of the issues I can remember:

• When we built the docker container for nr-server all the files in nr-common are outside of it's docker root and so they're not available in the container
• The dependencies in nr-common are not available in nr-server, so deno complains it can't find zod

Further issues where @babel/runtime is missing in nr-common which linked to this issue comment which is why I installed it into nr-common and fixed that error.
